Before this sweet girl -- in her plaid dress -- turned into an actress, she was just a brown-haired kiddo growing up in the land 'down under,' attending dance classes when she was only 4 years old ... and dreaming of becoming a big star one day!

Here's your last clue, in case you needed it 😜: "H20: Just Add Water" and you should be able to put a name to the unknown kiddo in question!
